Answering vaguely to honor the NDA. I was asked questions testing the in-depth understanding of the frontend and backend technologies that I had worked on. Some questions on problem solving. Some on writing test cases. Situational questions with examples from my past experience. My preferences on technologies and the type of teammates I want to work with.
Tell me about your experience and interest in automation testing
1. Hackerrank: 5 UI/FE related questions, two easy/average algo problems in JS (nothing like binary trees, etc. but a real-life problem), plenty of time to do this. 2. Code Review - I was tasked to conduct React/TS code review on a PR consisting of 4 files. The focus was not only on the functionality but on performance, accessibility, maintainability, and readability too. 3. Questions - UI/FE related questions inside Miro. You are presented with a wireframe and asked how would you code it (without actually coding it - you are just discussing). Other questions were focused on FE security, accessibility, etc. Be aware, that they are going to ask you more and more questions about a specific topic (going deep) until you are not able to answer - it's not bad to say "Yeah this I don't know anymore." 4. Behavioral Interview - classic behavioral questions like conflicts with colleagues, co-op styles, your failures, achievements, etc. They are going to send you a link to the STAR method before, so check that out - they expect you to answer according to this format here.
- Debounce Implementation - Debounce v/s Throttle - Remove Duplicates - const arr2 = [2, 1, 5, 2, 3, 2]; const S = 7; pair whose sum is >= S Given an array of integers, and a number ‘sum’, print all unique pairs in the array whose sum is > than ‘sum’. - const arr2 = [2, 1, 5, 2, 3, 2]; Replace each element with multiplication of rest of the elements, keeping in mind Time complexity (avoid nested for loops) - HOC, ForwardRef, ContextAPI
How to detect a loop in a linked list and memory optimization. Lots of questions on react. useState, useEffect, virtualDOM, etc.
Hooks in ReactJS
Data structure and algorithms (easy). Advanced Javascript and design patterns.
What are the disadvantages of CSS?
Both interviewers asked some standard questions about my coding style and preferences, and probed about my knowledge about development platforms (especially about their preferred platform, React).
